Christian Ryan – författare

This introduction to R for students of psychology and health sciences aims to fast-track the reader through some of the most difficult aspects of learning to do data analysis and statistics. It demonstrates the benefits for reproducibility and reliability of using a programming language over commercial software packages such as SPSS. The early chapters build at a gentle pace, to give the reader confidence in moving from a point-and-click software environment, to the more robust and reliable world of statistical coding. This is a thoroughly modern and up-to-date approach using RStudio and the tidyverse. A range of R packages relevant to psychological research are discussed in detail. A great deal of research in the health sciences concerns questionnaire data, which may require recoding, aggregation and transformation before quantitative techniques and statistical analysis can be applied. R offers many useful and transparent functions to process data and check psychometric properties. These are illustrated in detail, along with a wide range of tools R affords for data visualisation. Many introductory statistics books for the health sciences rely on toy examples - in contrast, this book benefits from utilising open datasets from published psychological studies, to both motivate and demonstrate the transition from data manipulation and analysis to published report. R Markdown is becoming the preferred method for communicating in the open science community. This book also covers the detail of how to integrate the use of R Markdown documents into the research workflow and how to use these in preparing manuscripts for publication, adhering to the latest APA style guidelines.

LONGLISTED FOR THE WILLIAM HILL SPORTS BOOK OF THE YEAR 2017''Exquisite'' Gideon Haigh''Magical, a head rush, a marvel'' Rahul Bhattacharya''Startlingly original'' Matthew EngelIn 1975 Patrick Eagar took some photographs which were unlike any cricket photographs anyone had seen before.It was the summer of an Ashes and a World Cup (cricket''s first), a near last-gasp summer before revolution when cricket was still a sport of helmetless faces and green fields with no advertising paint on them. A clamour of rare glamour descended on England: Thommo and D.K., baby-cheeked Viv Richards, careworn David Steele, lithe supercat Clive Lloyd, the Chappell brothers, Andy Roberts, Tony Greig, Doug Walters, trails of cigarette smoke gusting in his wake. From this raw material, a thirty-one-year-old with an expired Sports Illustrated subscription and a love of long lenses found something almost magical. Eagar''s pictures reveal that "feeling is the thing that happens in 1000th of a second". So this is a cricket book about photography and what it can do - tell the future and show human beings in ways not available to our eyes. It is part detective story, (and reconstruction of one of cricket''s greatest summers), part biography, part wild-roaming conversation, part essay on the power of the image, myth and reality. It shows Christian Ryan as one of the most elegant and perceptive writers on sport today.With seventy black-and-white and colour photographs by Patrick Eagar and other seminal photographers, it is is essential reading (and looking) for ardent fans and will exhilarate those who know nothing about cricket.
